Shape changes and large-amplitude collective dynamics in neutron-rich Cr isotopes
arXiv:1103.5270 · doi:10.1103/PhysRevC.83.061302
Abstract
Shape-phase transition in neutron-rich Cr isotopes around N=40 is investigated by employing the collective Hamiltonian approach. The inertial functions for large-amplitude vibration and rotation are evaluated by the local normal modes along the axial quadrupole collective coordinate using the Skyrme and pairing energy density functionals. The time-odd components of the mean fields are fully included in the derived masses. The low-lying spectra obtained by requantizing the collective Hamiltonian show an excellent agreement with the recent experimental data. Gradual change from spherical to axially deformed shapes in between N=34 and 38 is well described.
